The TL type high-efficiency heat exchanger is a copper tube through aluminum plate heat exchanger, which adopts advanced mechanical expansion tube and circular corrugated double flanged aluminum rib structure. Mechanical expansion tube and arc wave ripple double flanged aluminum rib structure form. Mechanical expansion of the tube ensures tight contact between the steel pipe and the aluminum rib, and the circular ripple can promote fluid turbulence, destroy the boundary layer, and improve the heat transfer coefficient. The advanced structural design, combined with reasonable waterway stroke, tube spacing, and plate spacing design, makes this heat exchanger have the characteristics of good heat transfer performance, low air resistance, compact structure, and light weight. It can be widely used in air conditioning, cooling, dehumidification, heating and other engineering projects. It is an ideal supporting product for air handling units and air handling units of fresh air units. It can also be connected to air ducts for separate use as cooling or heating.

Copper pipe welding adopts low-temperature rapid brazing to ensure pressure resistance>1.2Mpa.

This heat exchanger has a variety of blade spacing (2.5-3.6 millimeters) and a complete range of specifications to meet the needs of different working conditions and various combinations.

According to the theory of heat transfer, the maximum thermal resistance of a water air heat exchanger is on the air side. In order to increase the heat transfer coefficient, it is necessary to reduce the thermal resistance on the air side. The most effective method is to use boundary layer theory to increase the turbulent state of the air, that is, to increase the heat release coefficient on the air side. For this purpose, four advanced rib shapes have been designed:

● V-shaped rib ● V-shaped+slit ● Sine waveform ● Sine wave+bridge

The above four types of rib shapes can meet different process requirements of different users.
